Since the pentagon is regular, the sides are all of equal length. This tells you
... 5x-27 = 2x-6
... 3x = 21 . . . . . . . add 27-2x
... x = 7
The length of a side can be found by subtituting this value into either expression.
... 2·7-6 = 8 . . . . inches
Answer:
The answer to your expression is 94.
Step-by-step explanation:
Given Expression -> 3 ( 7 - 5 ) + 8 ( 9 + 2 )
Order of Operations Parenthesis -> 3 ( 2 ) + 8 ( 11 )
Multiplcation Left to Right -> 6 + 8 ( 11 )
Multiplcation Left to Right -> 6 + 88
Addition -> 94
The correct answer is 4,6.93,8
Using the pythagorus theorem
a2+b2 =c2
sqr(4)+sqr(6.93)=sqr(8)
Answer:
72
Step-by-step explanation:
you have to simplify both sides of the equation then isolate the variable
Answer:
2x + 8
Step-by-step explanation:
Don't worry, this is simple! Add up the common terms.
For example, you can't add up 2x and 5, because 2 is being multiplied by a variable.
So combine the x terms: 2x
And the numerical terms: 8
Combine 2x and positive 8.
2x + 8
